How Does Ilumya Block IL-23?

Tildrakizumab-asmn binds to the p19 subunit of interleukin-23 and blocks its interaction with the IL-23 receptor. This reduces signaling involved in release of proinflammatory cytokines and chemokines associated with plaque psoriasis.

Who Is Treated With Ilumya?

Ilumya is used in adults with moderate-to-severe plaque psoriasis who are candidates for systemic therapy or phototherapy. Patients are evaluated for tuberculosis before treatment, and age-appropriate immunizations are considered before therapy begins.

How Is Ilumya Dosed?

The recommended dose is 100 mg by subcutaneous injection at week 0, week 4, and every 12 weeks thereafter. Ilumya is administered by a healthcare professional. A missed dose is administered as soon as possible, followed by return to the regular schedule.

What Serious Risks Are Linked to Ilumya?

Serious hypersensitivity reactions, including angioedema and urticaria, can occur. Ilumya can increase infection risk, and treatment is not started in patients with a clinically significant active infection until the infection resolves or is adequately treated. Live vaccines are avoided during treatment.
